So I was arguing with this person online about something and then all of a sudden they decide to throw out something along the lines of "you're so cold-blooded". They were correct. In school we were always taught your average body temperature is 37 Degrees Celsius but mine is like 36. Therefore my blood is in fact colder than average. But how would someone I don't even know online would know? Is my personality very cold-blooded? How do i make my cold-bloodedness less obvious and more warm-blooded? Will my bloodtype change when i change my personality?
